Description

The NXF6501-Q100 is a specialized push-pull transformer driver that is designed to deliver low noise and low EMI for isolated power supplies in small form factors. This driver is capable of driving low-profile, center-tapped transformers from a 2.25 V to 5 V DC power supply, while achieving ultra-low noise and EMI through the use of slew rate control and Spread Spectrum Clocking (SSC).The NXF6501-Q100 comprises an oscillator and a gate drive circuit that produces complementary output signals to drive ground-referenced N-channel power switches. To ensure start-up under heavy loads, the device includes two 1.2 A power-MOSFET switches.The NXF6501-Q100 also features internal protection features such as current limiting, under-voltage lockout, thermal shutdown, and break-before-make circuitry, ensuring the device operates within safe limits. The device also includes a soft-start feature that prevents high inrush current during power-up with large load capacitors.The NXF6501-Q100 has a 440 kHz internal oscillator for applications that require higher efficiency and smaller transformer. The NXF6501-Q100 is available in a small 5 pin SOT8098-1 package and is characterized for operation within a temperature range of -55 °C to 125 °C.This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
